Abraham Sneden was the son of Robert Sneden and Mary Dobbs. He was born in 1733 in Westchester County, New York. At the time of his first marriage in 1759, he was making his living in Orange County, New York as a ferry operator at Sneden's Landing. His first wife had died by 1762. He married second Susannah Knapp on May 17, 1763 ("New York Marriages Previous to 1784", Albany, 1860, p. 381).

Abraham and Susannah had 4 known children who lived to adulthood:

Robert (1764 - ) m. Elizabeth Martin
Abraham (3 Mar 1767 - ) m. Catherine Knapp
Daniel (5 Jul 1769 - 1857)
Elizabeth (26 Mar 1778 - 7 Aug 1858) m. Captain Conrad Edict

Shortly after his second marriage, he and Joseph Knapp are listed as sureties for a marriage bond for Mary Clark, of Orange County, New York, and Joseph Knapp on August 10, 1763. On December 26, 1766, he is listed as a boatman from New York City when he was a bondsman for his brother Dennis Sneden for administration of their father’s estate (Scott, Kenneth, "Genealogical Data from New York Administration Bonds 1753-1799," Vol 10., New York, 1969). This may be in error because according to the "American Archives (Series), 1774-1777", page 592 by Peter Force published in Washington D.C., Abraham Sneden was living in Cornwall, Orange County, New York in 1775.
He is listed again as a boatman in the 1790 census for Haverstraw, Orange County, New York, which is located a few miles north of Sneden’s Ferry. He is listed along with his wife and 2 males over 16 and 5 females.
Around 1793 he moved to Conklin, Broome County, New York, settling at the mouth of Snake Creek. H. P. Smith lists him as one of the first settlers there in "History of Broome County" p. 187, Syracuse, 1885. J. B. Wilkinson states in "The Annals of Binghamton of 1840", Binghamton, 1967, pp. 66-7 that Abraham and Daniel Sneden lived 4 miles up the Susquehanna from Binghamton, and that Abraham Sneden, Jr. lived in Kirkwood. In 1798, Abraham Sneden, Abraham Sneden, Jr., and Daniel Sneden were among 37 persons who signed a petition addressed to Mr. William Bingham, the original proprietor of the Binghamton, New York area lands concerning the tile of their lands.
Abraham is listed as Abraham "Smithins" in the 1800 census for the Town of Chenango, Tioga County (which then included Broome County), New York. He and his wife are listed as over 45, along with 2 males, one between 16 and 26, and the other between 26 and 45. He is found living next door to David Compton.
He is found in the 1810 census as Abraham "Sneeden" for Union Township (which includes Conklin), Broome County, New York. He and his wife are listed as 45 and over, with one female between 10 and 15. He is living next door to his son Daniel.
He must have died before 1820 when he is no longer found in the census records for Orange County, New York.
He is also mentioned in the "Gazetteer and Directory of Broome and Tioga Counties, 1872-1873", which was self published in Syracuse, in 1872 by Hamilton Child.
